134 Mr. G. Lewis on new Japanese Histeride. 
striis 1-3 integris, 4-5 abbreviatis, 6 nulla; propygidio pygidioque 
grosse punctatis et immarginatis ; pedibus rufis. L. 4} mill. 
This species comes near to P. Lewist7; it is less convex, more 
parallel, with the fourth and fifth striz shortened from the 
middle; the pygidium is emarginate and convex. 
I obtained it from an oak near Bibi, in South Yezo, 
August 16, 1880. 
Platysoma rasile, n. sp. 
Oblongum, subparallelum, depressum, nigrum, nitidum, leve ; fronte 
concava, stria integra; pronoto lateribus sparse punctatis, stria 
pone oculos utrinque angulata ; elytris striis 1-3 dorsalibus in- 
tegris, 4-5 abbreviatis ; propygidio pygidioque fortiter punctatis. 
L. 32 mill. 
This species is very close to P. Leconted; it is more parallel 
and less quadrate, but the general sculpture above is almost 
identical. Beneath, the segments of the abdomen are of equal 
breadth, not contracted in the middle, as in P. Lecontec ; and in 
this particular there is a like modification to that hereafter 
noticed between HHister Arias¢ and Hister aino. : 
I took a few examples at Kumamoto and Konose in Higo.

Platysoma celatum, n. sp. 
Oblongo-ovatum, nigrum, nitidum ; fronte subconcava, stria recta ; 
pronoto antice rufo, lateribus punctulatis, stria transversa inter- 
rupta; elytris striis 1-4 integris, 5abbreviatis; propygidio pygidio- 
que punctatis ; antennis pedibusque rufo-brunneis. L. 3 mill. 
This species is allied to the preceding (P. rast/e), but the 
striation is different and also the coloration. 
Occurs in the vicinity of Yokohama in “ fir-stools”’ early 
in spring. 
Hister aino, nu. sp. 
Ovalis, convexus, niger, nitidus; pronoto lateribus late punctatis, 
stria integra, margine angusto, elevato ; elytris striis 1—4 dorsalibus 
integris, quinto et suturali abbreviatis ; propygidio sparse punc- 
tato, utrinque subfoveolato, in medio linea longitudinali distincta ; 
pygidio dense et grosse punctato. L. 8 mill. 
This insect in its general sculpture agrees with the rare 
European H. Arzasz, but it has not the subparallel outline of 
that species. This shortness or more ovate form as compared 
with H. Arias? arises from the structure of the abdominal seg- 
ments. In H. Arvas?, the segments of the abdomen beneath 
are of equal breadth ; in H. aino, the three median segments 
are narrow and only clearly visible at the sides, for in the
